How can I disable compiling some modules when I compile my kernel?

[tanakorn]

I want to compile my kernel without compiling some device modules. These devices do not appear in my kernel config file but they are still compiled.

I comment these device source code files in /usr/src/sys/conf/files.i386 but it still compiled.

How can I compile my kernel without compiling the device modules that I do not want?

Thank you.

Two ways:

1) build a custom kernel (edit the devices you do not need out of /usr/src/sys/i386/conf/GENERIC and save under a new name, then rebuild the kernel with that new configuration) -> http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html and/or see /usr/src/Makefile (you've done that, I see)

2) make.conf ->

MODULES_OVERRIDE
(str) Set to a list of modules to build instead of all of
them.


WITHOUT_MODULES
(str) Set to a list of modules to exclude from the build.
This provides a somewhat easier way to exclude modules you
are certain you will never need than specifying
MODULES_OVERRIDE. This is applied after MODULES_OVERRIDE.

For the first way, I tried it already. I found that in my GENERIC does not have that devices but it still compiled the source files. I am trying your second suggestion.

But this makes me confuse that why it still compiled when it does not appear in my GENERIC. And why it still compiled when I comment source files in /usr/src/sys/conf/files.i386

Thank you for help.

All modules will always be compiled, whether they are used or not. Only the make.conf settings can alter that behaviour. I don't believe /usr/src/sys/conf/files.i386 is meant to be used in the way you describe.

[tangram]

You might want to look at NOTES at /usr/src/sys/conf/NOTES. Or you could use LINT to see all options and use make.conf WITHOUT_MODULES to disable the ones you don't want.

Don't edit GENERIC, make a copy under a different name i.e. MYKERNEL and edit that.

[rtoma]

Also try man (5) make.conf in order to get more options for the build environment.

even i specified the modules that i won't be to be compiled with mu CUSTOM kernel i found it istalled with it .

WITHOUT_MODULES =


Remove the space before the "=".

@aragon
i still have the problem .

WITHOUT_MODULES
(str) Set to a list of modules to exclude from the build.
This provides a somewhat easier way to exclude modules you
are certain you will never need than specifying
MODULES_OVERRIDE. This is applied after MODULES_OVERRIDE.

this is what the man make.conf said ,think i have to set MODULES_OVERRIDE too but the goal of WITHOUT_MODULES in this case !

[aragon]

Is every single module that you've specified still being built? Or are some being skipped, but not others?

[gnemmi]

have you tried:


WITHOUT_MODULES="list of modules"


I've found some old info (http://lists.freebsd.org/pipermail/freebsd-doc/2007-August/012913.html) that suggests that WITHOUT_MODULES= could be set to a list of directories that contains the modules you want to exclude from the kernel compile, like so:


WITHOUT_MODULES= linux acpi sound/sound sound/driver/ds1 ntfs


those would be the directories found under /usr/src/sys/modules/

I, personally, never tried it though ...

[aragon]

WITHOUT_MODULES= linux acpi sound/sound sound/driver/ds1 ntfs


I believe that is the problem with SIFE's setup. One can't specify just the module name.

[gnemmi]

Yup ... I have that feeling too ..

[SIFE]

may be like what he did say mr onemmi ,setting full path for modules may work since i am going to disable all wifi ,sound and net card but OVVERIDE_MODULES for now is solution .
